(Kouwen's courseware)

Application of digital camera in total solar eclipse;

Digital camera: SLR, fools can use it to shoot solar eclipse.

Familiar with the use of cameras.

Shooting content:

Large-scale total food scenic belt landscape: wide angle, head.

Total solar eclipse photos with planets and bright stars. Wide angle, header.

Eclipse sequence: wide-angle lens, design in advance, arrange shooting angle and time interval.

The whole process of solar eclipse, Bailey bead, prominence, chromosphere, corona (inner corona, outer corona)

Gray light on the moon: the corona will be overexposed.

Other ground features.

Lens focal length: wide angle, medium focus and telephoto.

Choice of telescope:

Requirements for telescope: aperture, focal length and imaging quality.

It is suggested to use a short-focus refractor with a diameter of 60-80 mm and a focal length of 500 mm

Connection of telescope and camera:

Bayonet adapter ring, magnifying glass bracket, Nikon port, Canon port and so on.

Setting several important parameters of digital camera;

Shooting mode: manual

Exposure speed: 1/8000- 1 sec or more.

Aperture:

ISO setting: the principle is that the lower the better. It depends on the specific situation. Sensitivity is inversely proportional to exposure time. Setting the sensitivity too high will affect the image quality.

Image quality: adjust the pixels to the maximum.

Storage medium: CF card, capacity, spare. Make a plan in advance to ensure enough, and try not to change cards before and after the total solar eclipse to prevent accidents.

Battery backup: In order to ensure that the battery is fully charged, it is best to prepare more than two batteries. Be sure to confirm the battery charge before the total solar eclipse, and it is best to replace it.

Focus: Focus carefully with the help of sunspots. If there are no sunspots, you can only look at the edge of the sun, but it is very difficult, depending on your usual experience.

Conclusion: Be familiar with the camera you use. Others can't count on it at the critical moment.

The process of solar eclipse:

Initial loss: Take time to focus and test the exposure time as usual when shooting the sun. It is best to have an overall plan in advance, such as taking a picture every 3 or 5 minutes.

Eating: Take off the dimmer carefully a few minutes before eating, and prepare to grab the Bailey beads. Then gradually adjust the exposure time and shoot continuously. The exposure time gradually slows down from the fastest, for example: 1/8000 seconds-1 second.

Eat a lot: shoot as many times as possible during the total lunar eclipse, plan ahead, and arrange the exposure speed according to the length of the total lunar eclipse and the average speed of each shooting. It is recommended to speed up the exposure after eating too much.

Cold light: Before cold light, the exposure speed is accelerated to 1/2000s- 1/8000s, and Bailey Beads are ready to take a snapshot.

Last contact: after lighting, add a dimmer to shoot the partial solar eclipse.

Attention when shooting:

Dimming of telescope:

It must be firm, reliable, easy to take off and easy to install. Be safe.

Neutral density filter: 5-6cm in diameter (limiting the aperture of the telescope). Note: focusing is a problem. Due to the quality of the lens, it will affect the focal length.

Budd membrane: the most popular one at present.

0.012mm thick

Visual inspection: 5.0 dimming 10000 times.

Photography: 3.8

Using Budd's film to make a dimmer board requires more shooting and experience accumulation.

Improvise and be prepared according to the weather.

For example, it may be necessary to remove the dimmer when the weather is not very good.

Other methods are not recommended:

Smoked glass, waste film, welding piece, disk, ink dripping in water.

It is best to use wired release or remote control when shooting;

Minimize camera vibration.

There really is no such thing. When you press the shutter by hand, you must pay attention to your strength.

The environment in which the stent is placed is also very important:

Look for the north when placing the equatorial plane. There is no Polaris during the day, so you need a compass and a horizontal bubble.

The tripod should be placed firmly on the ground.

Do not interfere with each other and keep a certain distance.

Tip:

Be prepared in advance:

Master the observation of on-site eating and the start time of each stage.

Charge the camera battery in advance and empty the memory card.

Concentration: The key to success or failure is usually to accumulate experience. If possible, display the photos on the computer.

Be sure to remove the dimmer before the total solar eclipse! ! Remember! !

Never change the focal length when removing the dimmer.

Catch Bellevue: Catch the exposure time quickly.

Chromosphere: The exposure time should be fast.

Highlight: the exposure time should be fast.

Corona: from fast to slow, it exceeds 1/8000 seconds-1 second.

Bracket:

Portable equatorial plane, stable and firm tripod.

It's not necessarily electric tracking.

Be sure to consider the cost of carrying.

Skilled operation, usually practice more.

When choosing the observation site, we must pay attention to the direction of sunset, and there can be no shelter.

It's best for a person to do only one job, and not to be greedy for petty gain, and to look at one thing in a mess and do that thing badly.

These are all shooting methods under normal circumstances, and at the same time, we should consider contingency measures and flexibly adjust the plan according to the weather conditions.

Possible scenarios:

Weather conditions: cloudy, cloudy, foggy, poor atmospheric transparency, strong wind.

Equipment failure: bracket damaged, camera failure. (Standby state)

When observing the solar eclipse at 23: 09 on August 6, 2008, never look directly with the naked eye, let alone use a telescope. Even if there is a partial solar eclipse, when the sunlight is only blocked by a curved part, don't observe it directly with the naked eye, otherwise it will be hurt by strong sunlight.

Several methods commonly used by ordinary astronomy enthusiasts:

1 uses a solar filter specially designed for observing the sun.

Use exposed film as a filter.

Find a clean piece of glass and black it with a candle. 4 put water in the basin, add ink and look at the reflection.

● Eclipse shooting:

● In the partial eclipse stage before the total lunar eclipse, because it lasts for a long time, it is no different from ordinary partial eclipse, so the most important task at this stage is focusing. Be sure to repeatedly and patiently adjust the focal length to the best, so as not to leave regrets during the total solar eclipse. Focusing is purely an experience, and there are no shortcuts. It's good to have sunspots on the sun. If there are no sunspots, we can only rely on the edge of sun gear. Because the sun is too strong, the LCD screen may not be clear when playing, so prepare a wide and opaque coat in advance to cover the head and camera so as to watch the image more comfortably.

● When eating, the main subjects are Bailey beads and diamond rings.

Because the surface of the moon is uneven, when the moon enters and leaves the surface of the sun, the sunlight may leak out from a concave position on the moon and form a light bead in an instant, which is called Pirelli bead. Berry beads and colored balls, hanging in the sky like a diamond ring, have become the so-called diamond ring phenomenon.

Shooting Bailey beads means the beginning of the total eclipse phase, so take off the filter in advance. If you have accurate forecast time and station time, it is appropriate to remove the filter from 15 seconds to 1 minute before the eclipse, because there is only a little sun left at this time, and short-term direct light will not damage your camera. If you don't have the exact time, when you see only a faint sun point through the filter in the viewfinder, take it off.

Adjustment of exposure parameters: Since the time interval from the time when you remove the filter to the appearance of Bailey beads is less than one minute, it may be confusing to adjust the camera parameters at this time, so it is recommended that you adjust the camera parameters first, and then remove the filter. For specific parameters, please refer to the parameters about prominence in "Solar Eclipse Photographic Exposure Parameter Table".

By the way, when shooting Bailey pearls, you can already shoot chromosphere and prominence at the same time.

Bailey beads, chromospheres and prominences

● There are three main shooting targets in the total solar eclipse stage, one is the prominence, the other is the inner corona and the third is the outer corona. There are other stars.

On the periphery of the sun, there is a corona darker than chromosphere, which can only be observed during the total solar eclipse. The size of the corona will change with the movement of the solar magnetic field. At the peak of solar activity, the corona will be more obvious and wider. There are also some flame jets on the sun from time to time, called prominences. These prominences can only be seen during a total solar eclipse because their temperature is very low. Among them, the inner corona is as bright as the full moon, the outer corona is nearly 100 times darker, and the prominence is brighter than the inner corona.

During the total solar eclipse, there will be a moment of darkness, allowing observers to see bright stars in the sky.

The following "solar eclipse photography exposure parameter table" shows the exposure parameters of these three targets under different conditions, which has high reference value. However, it is not necessary to strictly follow this exposure meter in actual shooting. Exposure value can achieve good results by increasing or decreasing some, and at the same time, we should also consider the influence of clouds and fog in the sky and the height of the sun on the light intensity. In addition, because the outer corona may extend far beyond the diameter of a sun, in order to capture the whole corona as much as possible, we should try our best to ensure that the sun is in the center of the picture, and adjust the angle of the camera in time to make the long axis of the corona on the diagonal of the picture.

Another interesting project during the total solar eclipse was to photograph the earth on the moon.

Looking at the earth from the dark side of the moon during the total lunar eclipse is like a full moon, which is very bright. So the dark side of the moon will actually be illuminated by the earth, but the brightness is so much worse than the corona that we can't see it with the naked eye. However, if we greatly extend the exposure time, we can capture the details of the dark side of the moon. According to the experience, ISO 1600, 1/3 seconds exposure can take the whole picture of the earth under f/8 equipment, and you can set the exposure parameters flexibly according to your own specific conditions.

● Multiple exposures and post-stacking:

With multiple exposures of the camera, we can intermittently photograph the whole solar eclipse process on the same negative. Of course, post-multi-stack is used now. Pay attention to keep the tripod absolutely stable and use the cable to release it.

When shooting, we must first understand the path and span of the solar eclipse in the sky, so as not to let the sun out of sight before the shooting is completed. The span is generally within 90 degrees, and a 24mm lens is enough. To predict the route of the sun, make a shooting plan according to the duration and span, and determine when to start shooting, how often to shoot and when to end. The best composition is the diagonal of the negative.

A complete shooting may take dozens of times and several hours to finish. When the lens is directly facing the sun for such a long time, it is easy to burn out the shutter curtain and then burn out the photosensitive element. Therefore, it is necessary to prepare colored glasses in advance.

Multiple exposures should also strictly calculate the exposure of each sheet to prevent overexposure. If it is at night, we should also consider the light pollution in big cities. It is much easier to use digital post-superposition.

● Tips:

1 Make a careful plan in advance. For example, what camera, lens or telescope to use, what shooting method to use, what effect to shoot, and whether the photos taken later will have other applications besides appreciation, etc. Some creative photography needs special consideration. For example, just mentioned shooting a series of Sugar-Coated Berry, we must first choose a good location, calculate the time interval of each image and so on.

2. Conduct actual combat drills in advance. If possible, come to the actual observation site a few days in advance, and walk through the observation process from beginning to end while the solar eclipse occurs, including assembling the telescope, looking for the sun, connecting the camera, taking pictures, turning off the filter to take pictures (don't face the sun at this time), turning on the filter to take pictures, changing the memory card, changing the battery ... This can often find some unexpected minor problems, such as the device will get stuck when pointing at certain positions. It doesn't matter if you can't go to the observation site, you can practice anywhere, as long as you find the right time to make the height of the sun almost the height of the eclipse.

In actual observation, when there is a total solar eclipse or an annular solar eclipse, find a person to be responsible for telling the time. Because this stage lasts for a short time, and people are nervous and busy at this time, they often don't feel the passage of time, and the total solar eclipse or annular solar eclipse ends unconsciously. When someone tells the time specially, other observers can know the time and better arrange their own observations.

Don't forget to remove the filter during the total solar eclipse.
